In the event of a --------------------------------------- reorganization, recapitalization, stock split, stock dividend, combination of shares, merger, consolidation, rights offering, or any other change in the corporate structure or shares of the Corporation, the Board shall make such equitable adjustment, if any, as it may deem appropriate, in the number and kind of shares authorized by this Plan, or in the number, option price and kind of shares covered by the options granted. 8. Reallocation of options. Shares covered by options which expire ----------------------- or are terminated for any reason prior to being exercised in full may be reallocated by the Board. 9. Stock appreciation rights. ------------------------- (a) Grant. Stock appreciation rights may be granted by the Company under this Plan upon such terms and conditions as the Board may prescribe. A stock appreciation right may be granted only in connection with a nonqualified option previously granted or to be granted under this Plan. Each stock appreciation right shall 4 contain a provision that it shall become nonexercisable and be forfeited if the related option right is exercised. "Stock appreciation right" as used in this Plan means a right to receive the excess of the fair market value of a share of the Company's Common Stock on the date on which an appreciation right is exercised over the option price provided for in the related option right. Such excess is hereafter called "the differential." "Option right" means the right to purchase shares of the Company's Common Stock under a nonqualified option granted under the stock option plan. (b) Exercise of stock appreciation rights. Stock appreciation rights shall be exercisable and be payable in the following manner: (1) A stock appreciation right shall be exercisable by the optionee at any time the option to which it relates could be exercised. An optionee wishing to exercise a stock appreciation right shall give written notice of such exercise to the Company. Upon receipt of such notice, the Board shall determine whether the optionee's stock appreciation rights shall be paid in cash or Common Stock or any combination of cash and shares. Upon receipt of such notice the company shall deliver to the person exercising such right a certificate or certificates for shares of the Company's Common Stock which are issuable upon exercise of the stock appreciation right or cash or a combination thereof as the case may be. (2) The exercise of a stock appreciation right shall automatically result in the surrender of the related stock option right by the grantee on a share for share basis to the extent shares under such related stock option are used to calculate the shares or cash or combination thereof to be received by such grantee upon the exercise of such stock appreciation right. Shares covered by such surrendered option rights shall not be available for granting further options under this Plan. (3) The Board may impose any other conditions it prescribes upon the exercise of a stock appreciation right, which 5 conditions may include a condition that the stock appreciation right may only be exercised in accordance with rules and regulations adopted by the Board from time to time. (4) Upon the exercise of a stock appreciation right and surrender of the related option right, the Company shall give to the person surrendering the related option right an amount equivalent to the differential, in cash or shares of the Company's Common Stock or any combination thereof as determined in accordance with subdivision (b)(1) of this Section 9. The shares to be issued upon the exercise of a stock appreciation right may consist either in whole or in part of shares of the Company's authorized but unissued Common Stock or shares of the Company's authorized and issued Common Stock reacquired by the Company and held in treasury. No fractional share of Common Stock shall be issued and the Board shall determine whether cash shall be given in lieu of such fractional share or whether such fractional share shall be eliminated. 10. Discontinuance or amendment of the plan (and amendment of options). ------------------------------------------------------------------ The Board of Directors may discontinue this Plan at any time, and may amend it from time to time, but no amendment may, without further stockholder approval, (a) increase the total number of shares which may be purchased under the Plan other than as provided in paragraph 7, or (b) extend the period during which options may be granted or (c) change the class of persons to whom options may be granted, and no outstanding option may be revoked, or altered in any manner unfavorable to the holder, without the consent of the holder.
